MDA is what most ppl get, cos its earlier in the synth, and its good enough for most. something like 30-60% of all md substances found in pills depending on where u live.Results at ecstasydata.org do not seem to bear this out. True, it is biased towards pills which people found unsatisfactory in some way, rather than ones they enjoyed (and therefore consumed all that they bought, rather than having one to send in to be tested), but if MDA were really present in nearly half the pills on the market, more MDA would show up in the lab tests.
